I was constantly running into GPU Crashes with UE5 whether it was the preview 1 or 2.
I have a GTX 1080 Ti 11GB VRAM from Inno3D.
In my case, I just needed to download the Inno3D TunneIT OC program (MSI Afterburner if you got an MSI card) to set the “power” parameter.
Lowering the setting from 100% to 90% did not produce GPU crashes anymore, but I still got access violations regularly. When in doubt, I lowered the setting to 50% and ran the Epic Launcher and the Unreal Editor in administrator mode.
Since then, the editor is smoother and the system appears to be more resilient.
I think I could reasonably increase to 80% and get an equivalent result, it’s up to you
I hope this will help some of you, because I was a little annoyed that I couldn’t try all the new stuff.
